LIQUID DISPENSER.

Application filed January 24, 1923. Serial No. 614,533.

To all whom it may concern:

Be it known that I, WILLIAM A. SoHATz, a citizen of the United States, residing at Astoria, in the county of Queens and State of New York, have invented certain new and useful Improvements in Liquid Dispensers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to liquid dispensing apparatus, and more particularly in some of its details to such an apparatus especially adapted for cooling and dispensing beverages or similar drinks.

It is a general object of the invention to provide a liquid dispensing apparatus of the type having a closed exterior reservoir and an auxiliary reservoir extending into a cooling chamber, with an air-tight joint between the two, and an improved air admitting means carried by the reservoir for the admission of air when liquid is drawn off in' such a manner that air pressures within and with- 2 out the container are readily equalized.

Another object is to provide in an apparatus of the class mentioned an improved arrangement for the admission of air into the liquid container as liquid is drawn off, and

at the same time to effect agitation of the liquid within the container.

Other objects will be in part obvious in connection with the following detailed de scription of an apparatus embodying an exemplification of the invention, and in part pointed out in connection therewith.

The invention accordingly comprises the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the constructions hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a complete understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawing, in which there is shown a central vertical section of a dispensing apparatus embodying the invention.

Referring to the drawing for a detailed description of the embodiment shown, a base or supporting receptacle 1 is provided with side walls 2, preferably circular in horizontal projection and preferably also being suitably insulated. This base recep-.

tacle has an interior cooling compartment for the reception of a cooling medium, such as ice, and a top 3 and bottom 4 may also be suitably insulated. The top is preferably provided with an opening, with a cover 5 for the introduction of ice, for the inspection of the interior parts of the dispenser,

and for other purposes. An auxiliary container or cup 6 of earthenware or similar material preferably extends within the cooling compartment being suitably supported therein. An auxiliary wall extends from the bottom of the base 1 so as to contact with the auxiliary container and steady it in position. A discharge conduit 8 communicates with the auxiliary container extending through the cooling compartment and through the wall thereof, terminating in an exterior valve 9.

The auxiliary container traverses the cooling chamber preferablyextendinq through the top '3 thereof and terminating thereabove in an opening having a surrounding flange 10. This opening or mouth may be of any desired shape, but is preferably circular, and seated therein is a resilient washer or gasket 11 of corresponding shape and fitting over the flanged edges of the cup so as to form therewith a liquid and air-tight joint. In the preferred form of the invention the main liquid container 12 rests di rectly upon the resilient washer 11. The main container may, however, be partially or wholly supported by other means, the desirable feature being the formation of a liquid and air-tight joint between the two containers. The container 12 forms a reservoir for the liquid to be dispensed, and is entirely closed, except for a neck or conduit 13 which extends through the washer 11 into the cup 6, and a normally closed opening in the bottom, the purpose of which will be more fully pointed out hereinafter. A glass bottle is preferably employed for the main container, being inverted with the neck extending downwardly into the cup as stated. The weight of the bottle and contents, being thus supported on the resilient washer 11, assists in effecting the liquid and air-tight joint between the main and auxiliary liquid containers. The washer 11 is preferably of soft rubber, so as to intimately contact with the cup and main container under the weight of the latter, effecting the desired liquid and air-tight joint when the 11 forms an air-tight seal between the main bottle is placed in position. A liquid space is thus for m ed b y the main and auxiliary containers, of which the pipe 8 may be consideredanextension. When liquid is in the main container, 'a continuous unbroken liquid column occupies this space at all times, extending from the bottom of the auxiliary container to the surface of the liquid in the main container.

For the admission of air to the container 12 when liquid is withdrawn, so as to equalize pressures within and without the liquid space, an air-tube 14 is provided communicating with the exterior air pressure and directly with the interior of the'liquid space. As shown in the drawing, the bottle 12 is specially formed for supporting this air-tube in an integrally formed seat 15 in the bottom of the bottle, having an opening for thepassage of the tube. This seat is formed for the reception of a plug 16, in

which the air-tube 14 is mounted in supporting-relationship. For this purpose, it is convenient to form the plug 16 with an opening extending therethrough in which the tubeis frictionally gripped, so as to have its outer end in communication with the external air. This plug may be removed from its seat 15 when the bottle becomes empty, and the tube removed. The opening in the bottom of the bottle may then be conveniently sealed, as by the insertion of a convenient stopper, so the bottle may be shipped or stored with its liquid contents in the usual manner. The air-tube 14 extends down into the liquid column of the dispenser, preferably extending through the neck of the bottle and terminating well down within the auxiliary container. Y

Due to the fact that the resilient washer and auxiliary containers, air cannot enter the neck of the bottle except by the tube 14. The liquid in the auxiliary receptacle will therefore always remain in contact with the neck, rising thereabove to form with the liquid in the main container a continuous unbroken column. As the auxiliary container fills when the main container is inverted' thereon in the position shown in the drawing, liquid will pass from the main containerto the auxiliary container, filling the latter up to the lower edge of the bottle neck and slightly thereabove, the air in the space above the liquid becomingslightly compressed due to the-weight o'fthelliquid columnfabove. An air-chamber. is thus pros vided ,'fwhich acts as a cushion when iflow is checked and tends-to equalize the pressure at the draw off valve 9, consequently result-F ing in' a smooth discharge flow whenthe valye is opened. Due-to the fact that the air tube 14 extends down, within the liquid colu'mn, it will be seen that a multitude of small air-bubbles will, be discharged from.

tube carried-by saidmain liquid reservoirand' is oontinuously maintained 'within' said liq- .uid space.

the liquid column, .result in; a parti cula rly advantageous agitation within the liquid column, aerating the liquid in the dispenser and thoroughly mixing the contents in case the liquid is composed of different constituents. It will therefore be seen that it is advantageous to place the dischargefrom the air-tube well down within the liquid column.

From the above description it will be seen that the operation of the improved dispenser is substantially as in the open top type. The advantagesof looth the closed and open type of reservoir are thus obtained, while the disadvantages incident to the open type are avoided. When the bottle or main reservoir 12 is empty, the air tube is conveniently removed and the seat 15 readily sealed by means of anordinary cork and the utility of the bot-- tleas a shipping'or storing vessel is in no way impaired.

Since certain changes may bemadein the above construction and different embodiments of the invention could bemade without departing from the scope thereof,

it is intended that all matter contained in 9 theabove description or shown in the accompanying{drawing shall be interpreted as illustrative and not in a limiting sense.
